They are due out soon, not sure on the release date as those things are subject to change. No, I don't have one, I have a friend who has the original Trektop on his LJ, and he loves it, but he doesn't use his Jeep for much except a weekend cruise.
I understand that they are a bit more trouble to install/remove than a top with a frame, but most who have them say it's maybe 5 extra minutes. The biggest challenge will be if you want to carry it with you, expecting weather... They are bulky.
